invalid objectid:mongodb invalid object id (complete information)?

MongoDB ObjectId: MongoDB creates a unique 12 bytes ID for each object mistreatment the timestamp of several Object creation.This ObjectId is wont to unambiguously target a selected object within the database

Structure:

• 4-byte timestamp value

• 5-byte random value

• 3-byte incrementing counter (random value)

It looks like this, 507f191e810c19729de860ea

During a traditional backend work flow, the ObjectId may well be received supported some computation or user operations. These would possibly result invalid ObjectId and querying info with wrong ObjectId offers exception that is then handled later.

In this article, we are going to learn the way to visualise if a string is valid MongoDB ObjectId.

Examples:

594ced02ed345b2b049222c5 --> Valid MongoDB ObjectId
geeks --> Invalid MongoDB ObjectId

Prerequisites:

• NodeJS and NPM installed

Mongoose & MongoDB offer a really helpful perform in ObjectId i.e. ObjectId.isValid(“some_id”) to validate a string for proper MongoDB ID.

ObjectId is foreign from native mongodb as well as mongoose package.

Import ObjectId from mongodb or as well as mangoose packages:

Here some Import ObjectId from mongodb or mongoose packages: given below

• Using Mongodb:

const ObjectId = require('mongodb').ObjectId;
or
const mongodb, {ObjectId} = require('mongodb');

Using Mongoose:

const ObjectId = require('mongoose').Types.ObjectId;
or
const mongoose = require('mongoose');
ObjectId = mongoose.Types.ObjectId;Id;

String ID	ObjectId.isValid(id)	Expected Validation
594ced02ed345b2b049222c5	true	true
geeks	false	false
toptoptoptop	true     X	false
geeksfogeeks	true     X	false

If you want To prevent such cases,  then you must be added after default validator which would return true or false based on condition, (new ObjectId created from string) cast to string === string
i.e. (String)(new ObjectId(id)) === id
A function can be created as follows:seee the validity of functions

const ObjectId = require('mongoose').Types.ObjectId;
function isValidObjectId(id){
    
    if(ObjectId.isValid(id)){
        if((String)(new ObjectId(id)) === id)
            return true;
        return false;
    }
    return false;
}

• Javascript

// Requiring ObjectId from mongoose npm package const ObjectId = require('mongoose').Types.ObjectId;   // Validator function function isValidObjectId(id){           if(ObjectId.isValid(id)){         if((String)(new ObjectId(id)) === id)             return true;                return false;     }     return false; }   // Loading testcases into array const testStrings = [ "594ced02ed345b2b049222c5","geeks",                        "toptoptoptop","geeksfogeeks"];   // Validating each test case for(const testcase of testStrings){       if(isValidObjectId(testcase))         console.log(testcase + " is a valid MongodbID");     else         console.log(testcase + " is not a valid MongodbID");   }

Output:  Results of this function are:

String ID	isValidObjectId(id)	Expected Validation
594ced02ed345b2b049222c5	true	true
geeks	false	false
toptoptoptop	false	false
geeksfogeeks	false	false

Have you ever got curst MongoDB error invalid object id length? Here’s a fast fix.

MongoDB errors area unit common and troublesome to troubleshoot. This error chiefly happens because of variations within the ObjectId length necessities.

At Bobcares, we regularly receive requests to repair MongoDB error as a part of our Server Management Services.

Today, let’s have a deep check up on this error and its appropriate fix.

 MongoDB error invalid object id length” hidden indication behind it ?

A unique symbol helps to handle, access and act with one entity among the system.

For instance, the username or User ID provided to the new users once registering for an internet site is that the best example for UID. These UID area unit helpful for security and log functions that differentiate the user from different users.

ObjectID is that the default UID employed by MongoDB. Usually, this is often a 12-byte binary price, painted as a twenty four(24) character hex string.

These ObjectId’s helps to come up with UID in an exceedingly distributed system.

But, once the ObjectID length isn't twenty four characters, it throws the error “MongoDB error invalid object id length”.

How to fix invalid objectid:mongodb invalid object id easily?

Recently, one among our customers approached US with a MongoDB error. 

Half of the info has been regenerate to ObjectId however remainder of them failing with the error:

Invalid ObjectID length

Must be used this query-

db.booking.find({user: {$exists:true}}).forEach( function(x) {
    x.user = ObjectId(x.user);
    db.booking.update({_id: x._id}, {$set: {user: x.user}});
});

Our Support Engineers checked and located errors with the ObjectId length. this is often as a result of some information among them doesn't meet the length demand of the ObjectId.

We simply mounted this error by adding a where clause to the customer’s question as follows.

find({ user: { $exists: true }, $where: 'this.user.length === 24' })

It fixed above error.

Conclusion:

In short, MongoDB error invalid ObjectId length error happens once the info doesn't satisfy the length demand of ObjectId. In today’s write-up, we tend to saw this error intimately and conjointly mentioned however our Support Engineers fix it for our customers,Thank you.
